That is not a werewolf, Darkness. That appears to be a house. One of the clouds appears to be a hand.
Hm, well, you might try starting with a large, hulking muscle frame, sketch a couple body-builders for practice. For the legs, you want to keep the human thigh, but curve the end of it into a wolf's leg, then continue down with the rest of the leg being canine, lengthen the arms just a little and do talons on the hands instead of claws, and put a wolf's head where the human head would be, with fur trailing in a thicker mane down the back.
Easier said than done I guess...
